Where is my head

Yesterday I had to stop at the ATM to deposit some money before going to the airport. I forgot to put my wallet back into my laptop bag after that. I entered the terminal, cleared security, then went to buy a bottle of water because I didn’t bring my Kleen Kanteen. I started to pay for my purchase when I realized I didn’t have a wallet on me. I still had 30 minutes before boarding so I managed to get back out to my car, get my wallet and reclear security.

Just imagine if I hadn’t realized that until I landed at my connection.
